Example 1

At first the structure to the packaging body manufacturing system 200 of this example describes.

Fig. 1 is the schematic upper surface figure of structure example of the packaging body manufacturing system of the invention process form 1.Fig. 2 (a) and (b), (c) be respectively the IIA of Fig. 1 to view, IIB to view, IIC to view.

In Fig. 1, packaging body manufacturing system 200 forms unit Y by the packaging body linking belt X of manufacturing cell, scar and packaging body processing unit (sewing machine pinprick unit) Z constitutes.And set for the film F of band shape or by the packaging body linking belt PC of film F manufacturing and pass through according to the order that the packaging body linking belt X of manufacturing cell, scar form unit Y and packaging body processing unit Z.In the packaging body linking belt X of manufacturing cell, all sealing band 1A and periphery sealing band 1B, filling groove 2, component measurer 3, guiding roller 4, heatsealing device 5 and rotary drum 8 in setting are made packaging body linking belt PC by film F.Scar forms among the unit Y scar device 6 is set, and shown in Fig. 2 (c), forms scar 100 on the side edge part PF of packaging body linking belt PC.Z sets needle eye device 7 at the packaging body processing unit, shown in Fig. 2 (c), forms sewing machine pinprick 101 on the connecting part PA of packaging body linking belt PC.Here, the film F formations such as laminated film of resin film, resin film and metal foil laminates.Therefore, can carry out heatsealing described below.Again, on this film F, at the place of the regulation of following packaging body P printing mark M.

Here the structure to the device class that sets describes.

Rotary drum 8 forms cylindric, and S. A. extends upward at upper and lower, and periphery sets to shifting in the horizontal surface inward turning moving.And on the periphery of rotary drum 8, film F is folding, makes two imbricates of its side and Width, folding line below, upwards reel then in two edge.

In all sealing band 1A in the perisporium inboard of rotary drum 8, with the interval of the width that is substantially equal to packaging body P, dispose a plurality ofly at upper and lower with extending upward, rotate mobile with rotary drum 8.

Periphery sealing band 1B sets in pairs with interior all sealing band 1A, in the drawings, and finishing to sealing the Rotary District of a SE, with relative configuration of interior all sealing band 1A from sealing starting point SS.Again, between the Rotary District beyond the Rotary District of finishing a SE from sealing starting point SS to sealing (not shown), Yi Bian Yi Bian keep out of the way rotation downwards.

Interior all sealing band 1A and periphery sealing band 1B in the drawings, finishing the Rotary District of a SE to sealing from sealing starting point SS of rotary drum 8, rotate mobile on the periphery of rotary drum 8 while clip the interarea of folding film F.By means of this, on interior all sealing band 1A and periphery sealing band 1B the interval, on its whole width, carry out heatsealing to each regulation of the film F end wise that clips, form connecting part PA.Connecting part PA is with the border seal between the adjacent packaging body P, and the zone that separates between connecting part PA forms bag portion.Again, film F is clipped by interior all sealing band 1A and periphery sealing band 1B, utilizes the spinning movement traction of whole drum 8.

Filling groove 2 is equipped on the top between adjacent interior all sealing band 1A one by one, moves along the periphery rotation of rotary drum 8 synchronously with interior all sealing band 1A.And its lower end enters between folding film F.Introduce in the packaging body P of packaging body linking belt PC with this content that component measurer 3 is emitted.

Component measurer 3 when overlooking be with the perisporium of rotary drum 8 in the compartment of terrain configuration is a plurality of about equally with interior all sealing band 1A on the circumference that connects, and rotation is moved on circumference.And component measurer 3 is that to begin place FS in filling parallel above rotary drum 8 simultaneously between adjacent interior all sealing band 1A finish between the Rotary District of place FE to filling in the drawings.By means of this, the content in the component measurer 3 is filled in the packaging body P by filling groove 2.

Guiding roller 4 is near the outside of place SE is finished in the sealing that is in the downstream of rotary drum 8 on the circulating direction of packaging body union body PC and is equipped on rotary drum 8.By means of this, the packaging body linking belt PC of filling content is drawn towards in the heatsealing device 5.

Heatsealing device 5 is equipped on the downstream of guiding roller 4 on the flow direction of packaging body union body PC.Heatsealing device 5 forms has the structure of a pair of preheating bar 5A and die roll 5B respectively.And, set the structure that the side edge part that can be in regular turn the both sides of the edge of film F be overlapped to form for preheating bar 5A and die roll 5B clips.By means of this, carry out heatsealing near the lateral margin to film F, form the side edge part PF of the band shape of packaging body P.Also have, die roll 5B utilizes not shown rotary drive mechanism, and is synchronous with the spinning movement of rotary drum 8, packaging body linking belt PC introduced, in the opposite direction rotation.

Scar device 6 is equipped on the downstream of heatsealing device 5 on the circulating direction of packaging body union body PC.Scar device 6 forms the structure with working roll 6A, pressure roller 6B and not shown rotating driving device.Working roll 6A and pressure roller 6B are configured to its outer peripheral face side by side and roughly are in contact with one another.And the lateral margin that sets to clip the side edge part PF that utilizes the packaging body linking belt PC that heatsealing device 5 forms between this roller nearby passes through.Again, working roll 6A sets to not contacting with the side edge part PF packaging body P in addition of packaging body P.Place beyond the side edge part PF that can prevent like this at packaging body P forms scar and causes the content among the packaging body P to spill.

Shown in Fig. 3 (a) and Fig. 3 (b), working roll 6A is that plectane 6C multi-disc lamination on same axle of the thin gear-like of high-speed tool steel constitutes, here be that 4 laminations constitute, on the outer peripheral face of plectane 6C, form blade 6D in the whole week, the blade 6D of the short sword tread degree that extends on thickness direction is with the roughly interval formation of 2mm.By means of this, therefore the folded number of lamina of working accuracy increase and decrease plectane 6C that can instrument packaging body linking belt PC, can save useless blade 6D.

Again, the thickness lateral margin 0.45mm of plectane 6C.The thickness of plectane 6C is exactly the tread of blade 6D, packaging body P goes up the length of the scar 100 (with reference to Fig. 2 (c)) that forms again, therefore, according to the Kaifeng performance of the packaging body of the scar relation with tensile strength, the thickness of plectane 6C is 0.3mm～0.5mm preferably rule of thumb.The decline of the tensile strength of the packaging body P that scar causes can be suppressed with this, the easy opening of packaging body P can be accessed simultaneously.

And, when plectane 6C lamination, the blade 6D of adjacent plectane 6C is kept at interval.That is to say that the blade 6D of the short tread that the working roll 6A that plectane 6C lamination constitutes extends to about roll axial direction forms a plurality of on whole roll surface.Specifically, the blade 6D of adjacent plectane 6C is staggered, the blade 6D of adjacent plectane 6C is staggered.For example, blade 6D is staggered with respect to the formation position of the keyway of axis hole 6G for each plectane, make plectane 6C like this and get final product.

, shown in Fig. 3 b, between adjacent plectane 6C, clip the pad 6E lamination of 0.1～0.3mm left and right thickness here again.Like this, can on the blade 6D of adjacent plectane 6C, be formed up to the interval of the thickness size of rare pad 6E, therefore, can save the trouble that makes blade 6D stagger making plectane 6C and save cost.

Or the interior thickness that also can form plectane 6C is big, and the little structure of outer peripheral face thickness.For example, Fig. 4 (a) is the schematic plan view of another structure of working roll of the scar device of expression Fig. 1 of the present invention, and Fig. 4 (b) is the schematic side elevational view of another structure of working roll of the scar device of expression Fig. 1 of the present invention.Shown in Fig. 4 a and Fig. 4 b,, between central portion and outer edge, form step surface 6F in a side of the interarea of plectane 6C.Like this, step surface 6F correctly says at the periphery of plectane 6C, forms at interval between the blade 6D of plectane 6C adjacent on the blade 6D, therefore, blade 6D can be omitted the trouble of plectane 6C lamination with staggering, and can not want pad 6E.

The plectane 6C of lamination like this, not shown axle be by the axis hole 6G of band keyway, clamps from the two ends of axle to be fixed on the axle.

And, pressure roller 6B and working roll 6A and row arrangement and level and smooth outer peripheral face is contacted with the blade 6D of working roll 6A, therefore the side edge part PF through the packaging body linking belt PC of heatsealing device 5 is embedded between the roll surface of working roll 6A and pressure roller 6B.Here, working roll 6A and pressure roller 6B utilize the pressure configuration of spring that roll surface is in contact with one another.Again, utilize working roll 6A with side edge part PF by being partially submerged into of lateral margin, therefore, scar device 6 does not contact the packaging body P beyond the side edge part PF, the leak tightness of packaging body P needn't be worried to be damaged.

And rotating driving device drives working roll 6A and pressure roller 6B, with the spinning movement of rotary drum 8 synchronously with packaging body linking belt PC downstream side carry.That is to say that working roll 6A and pressure roller 6B rotate in the opposite direction, packaging body linking belt PC is introduced.

Needle eye device 7 is disposed at the downstream of scar device 6 on the circulating direction of packaging body union body PC.Needle eye device 7 forms has the structure that packaging body union body PC is clipped in the roller 7A of the band blade that sets and pressure roller 7B and not shown rotating driving device therebetween.Not shown rotating driving device makes pair of rolls 7A, 7B rotation, with packaging body union body PC side conveying downstream.That is to say, rotate in the opposite direction packaging body linking belt PC is introduced.Again, rotating driving device makes pair of rolls 7A, 7B rotation, and the blade of the roller 7A of band blade is contacted with connecting part PA.Set the sewing machine blade that forms the sewing machine pinprick on the roller 7A of band blade.On the connecting part PA of the packaging body linking belt PC of process needle eye device 7, form sewing machine pinprick 101 with this.Also have, also can replace the sewing machine blade, cutting knife is provided on the roller 7A of band blade, needle eye device 7 is replaced to the shutoff device that packaging body P is downcut from packaging body linking belt PC with this.Can also be deformed into by on the roller 7A of band blade, alternately setting sewing machine blade and cutting knife, go up and to form between the pinprick at interval from packaging body linking belt PC, the example that the packaging body P under the state of two packaging body P bindings downcuts.

The action example of the packaging body manufacturing system 200 of structure describes to having as mentioned above below with reference to Fig. 1 and Fig. 2.

At first the action example (packaging body linking belt Fabrication procedure) to the packaging body linking belt X of manufacturing cell describes.The band-like film F that is wound into the roller shape utilizes interior all sealing band 1A and periphery sealing band 1B to clip, and utilizes the spinning movement traction of rotary drum 8 to pull out.

The film F of pulling out then, is through on the drum of rotary drum 8.Specifically, shown in Fig. 2 (a), the both sides of the edge of film F are folded (overlapping processing) overlappingly, crease is down, and two edges of film F on the periphery that is wound on rotary drum 8 lastly.Again, when two imbricates of film F, the lower end of filling groove 2 enters in the middle of the film F.Also have, filling groove 2 is finished the back slippage upward of place SE in sealing on hand of rotation, above film F, arrives sealing beginning place SS in slippage downwards once again, revert to swing-around trajectory.By means of this, the lower end of filling groove 2 can easily enter between the film F.

Then, film F is between the Rotary District of finishing to sealing from sealing beginning place SS the SE of place, on the periphery of rotary drum 8 by interior all sealing band 1A with periphery sealing band 1B sandwiches and by heatsealing, be formed on the packaging body linking belt PC (connecting part processing) that is formed with heatsealing portion between the packaging body P.That is to say that packaging body P is shown in Fig. 2 (b), content that is filled with and the filling oral area FA in the upper end of folding film F are carried out sealing, and then the packing of content is finished.

Then, begin place FS and filling in filling and finish between Rotary District between the FE of place, from filling groove 2 by filling oral area FA filling content (filling treatment) in packaging body P.

Filling the packaging body linking belt PC of content under the guiding of guiding roller 4, leave rotary drum 8, by heatsealing device 5.At heatsealing device 5, the filling oral area FA of film F is preheated the preheating of bar 5A institute, utilizes die roll 5B heatsealing through fore-warming filling oral area FA, forms side edge part PF, forms concavo-convex surface (side edge part processing) simultaneously on side edge part PF.By means of this, finish packaging body P in connecting part PA and side edge part PC sealing formation, constitute packaging body linking belt PC.

Action example (scar formation operation) to scar formation unit Y describes below.Packaging body linking belt PC is by scar device 6.At scar device 6, side edge part PF is embedded into and forms scar 100 among working roll 6A and the pressure roller 6B.Then, packaging body linking belt PC embeds the working roll 6A rotation of side edge part PF when its link direction is transferred, and the blade of working roll 6A embeds side edge part PF in regular turn and forms new scar.By means of this, the lateral margin of the side edge part PF of packaging body P nearby forms the elongated scar on a plurality of directions that are approximately perpendicular to lateral margin, and therefore, packaging body P is called the packaging body of easily openable.

At last, the action example (sewing machine pinprick operation) to packaging body processing unit Z describes.Packaging body linking belt PC is drawn towards needle eye device 7.At needle eye device 7, be formed on the connecting part PA between the packaging body P and be formed sewing machine pinprick 101, become the packaging body linking belt PC shown in Fig. 2 (c).

According to top described, packaging body manufacturing system 200 of the present invention can be used the film F that does not form scar, the lateral margin that is manufactured on side edge part PF nearby forms the easy-open package P that is approximately perpendicular to a plurality of elongated scar 100 on this lateral margin direction, therefore, can reduce the manufacturing cost of easy-open package P, shorten the manufacturing leading time of easy-open package P.Again, during packaging body P sealing, packaging body P is not processed to easy-open package, therefore by regulating the resistance of pulling out of film F, applies tensile force on the film F that is introduced into rotary drum 8, can revise the position deviation of the mark M of the film F when being introduced into rotary drum 8.That is to say that the position of the film F in the time of can adjusting packaging body P manufacturing so that be printed on the position of the lip-deep mark M of packaging body deviation does not take place.

Example 2

Example 2 is that possessing at content is under the situation of one, the example of the packaging body linking belt X of manufacturing cell that is suitable for using.The structure that scar forms unit Y is identical with example 1 with action, so scar forms the structure of unit Y and the explanation of action is omitted.

Fig. 5 is the schematic perspective view of structure example of the packaging body manufacturing system of expression the invention process form 2.In Fig. 5, identical with Fig. 1 or cooresponding part is marked with identical symbol and omits its explanation.

Packaging body manufacturing system 210 forms unit Y and packaging body processing unit (cutting unit) Z formation by overall arrangement in the packaging body linking belt X of manufacturing cell, the scar that vertically are vertical direction.And, be configured to banded film F or the packaging body linking belt PC that made by film F can pass through the packaging body linking belt X of manufacturing cell in regular turn, scar forms unit Y and packaging body processing unit Z.In the packaging body linking belt X of manufacturing cell, be equipped with nip rolls 15, guiding roller 4, ways 10, filling nozzle the 11, the 1st heatsealing roller 12 and the 2nd heatsealing roller 13, make packaging body linking belt PC by film F.Be equipped with conveying roller 9 and shutoff device 14 among the packaging body processing unit Z, downcut packaging body P at the connecting part PA of packaging body linking belt PC.

Here the structure to the device class that sets describes.

Nip rolls 15 set to can pull out film F from roller, and guiding roller 4 sets to it being guided into ways 10.

Ways 10 is the members with U font frame, and such frame is set on general horizontal direction.Then, in frame, film F is passed through from the top down.By means of this, make film F both sides of the edge flexing relatively.

The 1st heatsealing roller 12 forms the structure with 1 pair roller and not shown rotating driving device, on the outer peripheral face of each roller, at axial two places,

protuberance

12A, 12B form flange-like, at

protuberance

12A, 12B, roller be in contact with one another and make S.
